[0029] The present utility model provides a new type of excavator bucket 100.

[0030] Please refer to Figure 1 - Figure 5 , in an embodiment of the present utility model, the new type of excavator bucket 100 includes a bucket body 10, a tooth structure 20 and a limiting member 30. An accommodation groove 11 is provided at one end of the bucket body 10 in contact with the ground. The tooth structure 20 is installed in the accommodation groove 11, and the teeth 22 on the tooth structure 20 are exposed outside the bucket body 10. A first positioning hole 12 is formed in the bucket body 10, and the first positioning hole 12 communicates with the accommodation groove 11. The limiting member 30 passes through the first positioning hole 12 and abuts against the tooth structure 20. When the limiting member 30 is disengaged from the first positioning hole 12, the tooth structure 20 can move in the accommodation groove 11, and the part of the tooth structure 20 exposed outside the bucket body 10 can be completely retracted into the accommodation groove 11. It can be understood that when the soil shoveling work is completed and the bucket body 10 is used to trim the surface of the excavated soil, the tooth structure 20 is retracted into the accommodation groove 11 so that there will be no tooth marks left on the soil surface.

[0031] In this embodiment, the tooth structure 20 includes a long plate 21 and a plurality of teeth 22. Each tooth 22 is arranged at intervals on the long plate 21 and is perpendicular to the long plate 21. Among them, each tooth 22 and the long plate 21 are made of steel structures processed, and the tooth 22 and the long plate 21 are connected together by welding, and its firmness meets the working implementation standard.

[0032] Two connecting ear plates 16 are provided above the bucket body 10 for connecting the operating arm of the excavator to control operations such as shoveling soil for the bucket body 10.

[0033] In one embodiment of the utility model, a second positioning hole 13 is provided on the shovel body 10, and the second positioning hole 13 is also connected to the accommodating groove 11, wherein the second positioning hole 13 is located on one side of the first positioning hole 12, the first positioning hole 12 is relatively far away from the port of the shovel body 10, and the second positioning hole 13 is relatively close to the port of the shovel body 10; the shovel body 10 is also provided with a baffle 40, the baffle 40 is located at the exit of the accommodating groove 11 to block the accommodating groove 11, and a notch 41 is provided on the baffle 40 corresponding to each bucket tooth 22, the bucket tooth 22 passes through the notch 41 and is exposed outside the shovel body 10, and the baffle 40 can resist the long plate 21 to prevent the long plate 21 from falling out of the shovel body 10.

[0034] A through hole 23 is formed on the long plate 21 . When the limiting member 30 is separated from the first positioning hole 12 and passes through the second positioning hole 13 and the through hole 23 , the bucket tooth 22 is completely retracted in the accommodating groove 11 .

[0035] In this embodiment, the limiting member 30 is a long solid steel bar, and the size of the through hole 23 is consistent with the size of the first positioning hole 12 and the second positioning hole 13, thereby reducing the gap between the limiting member 30 and the long plate 21 and reducing the amount of shaking. It can be understood that when shoveling is required, the limiting member 30 is stuck in the first positioning hole 12. At this time, the limiting member 30 is against the end of the long plate 21 to limit it, so that when shoveling is performed, the bucket tooth 22 will not retract into the receiving groove 11. After the shoveling is completed, when it needs to be flattened, the limiting member 30 is pulled out of the first positioning hole 12, and then the bucket tooth structure 20 is pressed down against the ground by controlling the excavator, so that the bucket tooth structure 22 retracts back into the receiving groove 11. At this time, the second positioning hole 13 is aligned with the through hole 23, and then the limiting member 30 is inserted into the second positioning hole 13 and fixed through the through hole 23. At this time, the bucket tooth 22 is in a state of being completely retracted in the receiving groove 11, and under the limitation of the limiting member 30, it will not pop out of the shovel body 10. When the shovel body 10 is used to trim the excavated soil surface, no bucket tooth marks will remain on the soil surface.

[0036] In one embodiment of the utility model, a positioning column 17 is provided on the side wall of the accommodating groove 11, a sliding groove 24 is opened on the long plate 21, the positioning column 17 is stuck in the sliding groove 24, an elastic member 18 is provided in the sliding groove 24, and the elastic member 18 is against the end of the positioning column 17.

[0037] In this embodiment, the positioning post 17 is arranged perpendicular to the side wall of the receiving groove 11, and its end faces the notch 41. The elastic member 18 can be a spring, but is not limited thereto. It can be understood that when the bucket tooth 22 retracts into the receiving groove 11, the long plate 21 presses the elastic member 18. When the limiting member 30 is pulled out of the second positioning hole 13, the elastic member 18 restores its elasticity and pushes the long plate 21 back, so that the bucket tooth 22 can automatically pop out and be exposed outside the shovel body 10 without manual reset, which is convenient for operation.

[0038] In an embodiment of the present utility model, a first threaded hole 14 and a second threaded hole 15 are formed in the shovel body 10. The first threaded hole 14 is located above the first positioning hole 12, and the second threaded hole 15 is located above the second positioning hole 13.

[0039] In this embodiment, the limiting member 30 is provided with a boss 31, and a fixing member 32 is provided on the boss 31. The fixing member 32 can be a common screw. The fixing member 32 is threadedly connected to the first threaded hole 14 or the second threaded hole 15 to fix the limiting member 30 to the shovel body 10.

[0040] When the limiting member 30 is stuck in the first positioning hole 12, the fixing member is stuck in the first threaded hole 14. When the limiting member 30 is stuck in the second positioning hole 13, the fixing member 32 is stuck in the second threaded hole 15.

[0041] Working principle: When shoveling soil, the limiting member 30 is stuck in the first positioning hole 12, and the fixing member 32 is stuck in the first threaded hole 14 to fix the limiting member 30. At this time, the limiting member 30 abuts against the end of the long plate 21 for limiting, so that the bucket tooth 22 will not retract into the receiving groove 11. After shoveling the soil and needing to level it, the fixing member 32 is detached from the first threaded hole 14, and then the limiting member 30 is pulled out of the first positioning hole 12. Then, by controlling the excavator, the bucket tooth structure 20 is pressed downward against the ground, so that the bucket tooth structure 20 retracts into the receiving groove 11. At this time, the second positioning hole 13 is aligned with the through hole 23, and then the limiting member 30 is inserted into the second positioning hole 13 and passes through the through hole 23, and the fixing member 32 is fixedly connected to the second threaded hole 15. At this time, the bucket tooth 22 is completely retracted in the receiving groove 11. When using the shovel body to trim the surface of the excavated soil, there will be no bucket tooth marks left on the soil surface.

[0042] The above are only the preferred embodiments of the present utility model, and thus do not limit the patent scope of the present utility model. Any equivalent structural transformation made under the inventive concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present utility model.
